A fuel gas containing 95 mole% methane and the balance ethane is burned completely with 25% excess air. The stack gas leaves the furnace at 900°C and is cooled to 450°C in a waste-heat boiler, a heat exchanger in which heat lost by cooling gases is used to produce steam from liquid water for heating, power generation, or process applications. (a) Taking as a basis of calculation 100 mol of the fuel gas fed to the furnace, calculate the amount...

A fuel gas containing 85.0 mole% methane and the balance ethane is burned completely with 15.0 % excess air. The stack gas leaves the furnace at 900.0 °C and is cooled to 450.0 °C in a waste-heat boiler, a heat exchanger in which heat lost by cooling gases is used to produce steam from liquid water for heating, power generation, or process applications. Physical Property Tables Combustion Gases Correct. Take as a basis 100.0 mol of the fuel gas fed...

coal is fed at a rate of 40000 kg/h and has an ultimate analysis of
76wt% C, 5wt% H, 8wt% O, negligible amounts of N and S, and 11wt%
non-combustible ash. Air enters a preheater at 30 °C and 1 atm with
a relative humidity of 30%, exchanges heat with the hot flue gas
leaving the furnace and air enters the furnace at temperature Ta
(°C). The flue...

A fuel gas that contains
mole% methane and the balance ethane is burned completely with
pure oxygen at
°C, and the products are cooled to
°C.
suppose that the combustion takes place in a constant-volume
batch reactor. Take
mol as a basis of calculation of the fuel gas charged into the
reactor and assume any percent excess oxygen,
and calculate –Q(kJ) for the cases of liquid water as
well as water vapor as products.

In a laboratory experiment 78.612 g of methane is burned in air containing O2 to form gaseous CO2 and H2O. Calculate the final temperature in °C of the product mixture if the methane and air are both at an initial temperature of 4.9°C. Assume a stoichiometric ratio of methane to oxygen from the air, with air being 21% O2 by volume and the rest of the volume being N2 (c of CO2 = 57.2 J/molK; c of H2O(g) = 36.0...

Fuel is burned in a boiler to produce saturated steam at 10.0 bar absolute pressure from saturated liquid water at 10.0 bar absolute pressure. This H20 flows through tubes that run through the boiler, Energy released by combustion is transferred as heat through the walls of the tubes to convert the liquid water to steam at 10.0 bar. The fuel consists of 37 mol% ethane and 63 mol% acetylene, and is fed in the vapor phase at 50 °C and...

A fuel gas that contains
mole% methane and the balance ethane is burned completely with
pure oxygen at
°C, and the products are cooled to
°C.
Suppose that the reactor is continuous. Take a basis of
calculation of
mol/s of the fuel gas, assume some value for the percent excess
oxygen fed to the reactor (the value you choose is not going to
affect the results), and calculate -Q⋅ (kW), the rate at which heat
must be transferred from the...

A liquid fuel containing C, H and O, was burned completely using excess air. The Orsat analysis of the combustion gas shows 4.48% CO2, 11.21% O2 and 84.31% N2, And the molal humidity of the product gas is 0.179 mol water vapor per mol of dry gas. Calculate % composition by weight of the liquid fuel.
